Choose an IGCSE Co-ordinated Sciences tutor who teaches all three sciences at Cambridge 0654 level, knows whether your child sits Core or Extended, and prepares them for the practical or alternative to practical paper. Co-ordinated Sciences is a double award that earns two grades, while Combined Science (0653) is a single award. Both mix biology, chemistry and physics, so a student can be strong in one and weak in another. This guide explains how to choose a tutor.

Written by Tutopiya, an online tutoring company that teaches Cambridge IGCSE sciences one-to-one.

Key takeaways

• 0654 earns two grades; 0653 earns one.
• Check Core or Extended entry with the school.
• Find the weakest of the three sciences first.
• Practical skills are assessed and must be practised.

What is IGCSE Co-ordinated Sciences?

Cambridge IGCSE Co-ordinated Sciences (Double Award, 0654) is a science qualification that covers biology, chemistry and physics in separate syllabus sections and awards two grades. Combined Science (0653) covers the same three sciences as a single award. Both are described on Cambridge’s Co-ordinated Sciences page.

	Combined Science (0653)	Co-ordinated Sciences (0654)	Separate sciences
Grades	One	Two	One per science (three)
Content	Least	More	Most
Common route	Broad science	Most students	Future scientists
Practical skills	Assessed	Assessed	Assessed

Which science is the weak one?

Most Co-ordinated Sciences students have one weaker science, often physics or chemistry calculations, and tutoring works best when it targets that science first. Look at recent test results by section rather than the overall mark.

Common trouble spots:

• Chemistry: moles, equations and electrolysis.
• Physics: equations, units and graphs.
• Biology: precise terms and extended answers.

Our IGCSE Co-ordinated Sciences tutors in Dubai typically start by checking all three quickly.

Core or Extended?

Extended students can reach the top grades, while Core entry caps the grades available, so the tier affects what the tutor teaches. Ask the school which tier your child is entered for. Our guide to IGCSE Core or Extended tutoring explains the decision.

How to choose a Co-ordinated Sciences tutor: step by step

1. Confirm the syllabus: 0654 or 0653, and the tier.
2. Identify the weakest science from school tests.
3. Book a trial lesson on a topic from that science.
4. Ask how the tutor teaches practical skills.
5. Check past-paper use with mark schemes.
6. Agree a plan that balances all three sciences.

What should a good science tutor offer?

What to check	Why it matters
All three sciences	Saves juggling tutors
Tier awareness	Core and Extended differ
Practical skills	Assessed in a separate paper
Calculation practice	Common source of lost marks
Mark-scheme language	Precise terms earn marks

Practical skills: practical test or alternative to practical

Students sit either a practical test or a written alternative to practical paper, and both reward planning, measuring, recording and evaluating experiments. Tutors can’t run lab work online, but they can teach the written skills thoroughly. See our guide to an IGCSE alternative to practical tutor.

What does a good lesson look like?

1. A quick recap of the previous topic.
2. One weak topic taught clearly.
3. Past-paper questions, including a calculation.
4. Marking with the mark scheme.
5. A short task for the week.

Signs your child needs help

• one science much lower than the others;
• calculations costing marks;
• vague answers in longer questions;
• unfamiliar with practical-style questions.

Is Co-ordinated Sciences enough for A Level sciences?

Many sixth forms accept Co-ordinated Sciences for A Level sciences, especially at good grades, but requirements vary, so check with the school your child plans to attend. Students moving from double award to A Level Chemistry or Physics often need extra work on calculations and depth. A tutor can bridge that gap in the summer before Year 12.

How parents can help

• ask which science feels hardest, not just how science is going;
• check that homework includes past-paper questions;
• note mock results by science section;
• keep the exam timetable visible so revision covers all three sciences.

Questions to ask a science tutor

1. Do you teach all three sciences at IGCSE level?
2. Have you taught 0654 or 0653 specifically?
3. How do you prepare students for the practical or alternative to practical paper?
4. How will you split time between the three sciences?

How much tutoring is enough?

One hour a week usually covers one weak science well; students with two weak sciences may need ninety minutes or two shorter sessions. Increase before mocks and in the final term, then reduce once results are steady.

Common mistakes

• Treating science as one subject → find the weakest science.
• Ignoring the tier → confirm Core or Extended.
• Skipping practical questions → practise them regularly.
• Leaving calculations → practise them every week.

Frequently asked questions

What is IGCSE Co-ordinated Sciences? +

Cambridge IGCSE Co-ordinated Sciences (Double Award, 0654) covers biology, chemistry and physics in separate syllabus sections and earns two grades. Combined Science (0653) covers the same three sciences as a single award, earning one grade.

Is Co-ordinated Sciences easier than separate sciences? +

It covers less content than taking Biology, Chemistry and Physics separately, but the questions still need precise science. Students aiming for A Level sciences should check what their sixth form requires.

Can one tutor teach all three sciences? +

Often, yes. Many tutors teach all three at IGCSE level. If one science is much weaker, a specialist in that science can help more.

Are there practical exams? +

Practical skills are assessed through either a practical test or an alternative to practical written paper, depending on what the school enters. A tutor can prepare students for either.

Does Tutopiya offer Co-ordinated Sciences tutors? +

Yes. Tutopiya offers one-to-one online IGCSE Co-ordinated and Combined Science tutoring. The first trial lesson is free with no card required.
